Comprehensive Transformer Characteristics Testing Instrument is specially designed for relay protection professionals to test the volt-ampere characteristics, transformation ratio, and polarity of current transformers. It can also be used for transformer polarity discrimination tests, making it a multifunctional testing instrument with a high performance-to-price ratio.
This instrument adopts high-efficiency, low-consumption quality materials and a specially wound voltage booster, with a microcontroller microprocessor for data acquisition, analysis, and storage. It comes with a built-in micro printer that can print test data and curves. When measuring CT transformation ratio, it can automatically calculate the ratio value. One person can complete all testing tasks. This instrument is lightweight, easy to operate, and has unique performance, making it an indispensable tool for field personnel.
